i like the ones that you can turn into an algebra equation and then just plug it into the exponential

those are boss

Look it's been 10 years since I got my engineering degree. I barely remember what is a differential equation, I'm light years away from being able to solve one.

sadly those are 0,0001% of differential equations that you encounter in real life

just make sure you apply the proper initial conditions and boundary conditions and plug in the general formula and take derivatives as needed

Look at the chapter, do examples and practice problems. Do it at a library and do it till you're good at it

yup
there is a theory that lets you investigate analytic solutions but it's way over most people's heads (I guess it would be called functional analysis)

Not OP, but as a Computer Science major, Am I missing something if I don't take differential equations?

You're missing something if you still think you will be happy wageslaving. Do what interests you, not what you think you have to do to be attractive to an employer.

just linearize around the current state and assume its valid for your case
